This is an automatically generated message. An error has\n\
been found in your .forward file. Details of the error are\n\
reported below. While this error persists, you will receive\n\
a copy of this message for every message that is addressed\n\
to you. If your .forward file is a filter file, or if it is\n\
a non-filter file containing no valid forwarding addresses,\n\
a copy of each incoming message will be put in your normal\n\
mailbox. If a non-filter file contains at least one valid\n\
forwarding address, forwarding to the valid addresses will\n\
happen, and those will be the only deliveries that occur.
